Machine is a Windows 7, SP1.

In Device Manager>Portable Devices, there are four icons, G, H, I, and J,
with the yellow exclamation triangle.

The General tab for each one says, "This device annnot start. (Code 10)"

The Details tab for each shows:

G:\ SD/MMC
H:\ Compact Flash
I:\ SM/xD-Picture
J:\ MS/MS-Pro

I've had those types of portable devices attached to this machine at one time or another, but not lately. Right now, I've got USB flash drives and a USB
My Book external HD attached.

Interesting that the My Book shows up as My Book (H:) in File Explorer, and that all USB ports work fine.

Uninstalling or updating the drivers show that the best drivers are already installed.

All four show drivers are:

(1) C:\Windows\System32\DRIVERS\UMDF\WpdFs.dll, and
(2) C:\Windows\System32\DRIVERS\WUDFRd.sys

I can find (1) on my drive, but not (2).

I thought UsbTreeView would shed some light on this, but it didn't, at least not that I know of.

How can I eliminate these icons?

Thanks.

That's a USB card reader, sometimes stuffed by Dell into the floppy mounting hole.
The plate for that, has room for SD, MMC, and so on. They have names such as "52-in-1 card reader", but the max number of drives it supports is four.
The holes on the front, some of the holes support more than one format,
which is how the options manage to add up to 52 in total.

Typical USB card readers, show one disk letter (the one I own) or
four disk letters (Dell card reader).

If the cable leading from the assembly was unplugged, that might prevent it from
hogging drive letters. But that's a pretty extreme solution (don't bother).

The "Folder Options" dialog from File Explorer, in the advanced settings where you would click "Hide extensions of known file types" when the computer is new to you. Well, right next to that setting is:

"Hide empty drives"

That would be good for a card reader, not so good
for the optical drive in your desktop. You'd have to
stuff media into the optical drive, before the drive letter
would show up.

When you plug in a USB device, presentation data is stored in the
registry for the device. USB devices get enumerated, so they can be
quickly recognized when later plugged it. For example, Windows will try
to reassign the same drive letter for a USB flash drive if the drive
letter is currently available. Enumeration data is stored in the
registry at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\USB*

Sometimes the presentation data is corrupted, or doesn't match what got recorded when the USB device is later inserted. A fix is to delete the enumeration data in the registry for the device, and plug in the device
again for the handshaking to redeliver the presentation data.

USBDevView by Nirsoft will show which USB devices have been recorded,
and which are currently connected. Rather than edit the registry to
delete old or inaccurate enumeration data, you can use USBDevView to
delete a device which removes its enumeration data from the registry.

I used USBDev with admin permissions. The only one of the four icons that showed up as connected in USBDev was the SM/xD-Picture. None of the other three appeared in the listing. I highlighted it, and clicked "Disconnect Selected Devices", and restarted. All four icons re-appeared.

Next, I highlighted SM/xD-Pictures again, and this time selected
"Uninstall Selected Devices", and restarted. This time, as Windows
rebooted, a notification said to the effect, "installing software
drivers", and the four icons were back again.

Hmmm...So I decided to try again, but this time I selected "Disable
Selected Devices". I restarted, and the four icons were gone.

Next, I did a Shut down (rather than a restart), and the four icons were
still gone.

I wonder why only the SM/xD-Pictures was the only of the four icons that appeared in USBDev, and disabling it removed all four icons.

Many thanks for the help.
